I have to deal with this segmentation fault every now and then. Every time a model is not very basic, then displaying cells, graphs or anything else leads to a segmentation fault. Is there a way to be sure that the memory we attibute to each variable is high enough to avoid this error. Is there a patch somewhere to face this bug? Regards, Laure

Segmentation fault occurs due to memory problem (may be insufficient RAM.You can try the following 1.upgrade the RAM. (As per your problem size) 2.Resize your param.prp file. 3.last option is delete the param.prp file and open your model. (while open the model param.prp file will be automatically created. 4.Insted of using 3.26 you can use 3.24 or 3.22 which are very stable.
